池善豪 우석대학교 의과대학 1967 우석의대잡지 Vol.4 No.1

To investigate influences of head injury on the cardiovascular function, the electrocardiograms were examined in a total of 70 cases of head injury without pre-existing cardiovascular disorders. In 60 of 70 cases, the electrocardiograms were examined either before or after the craniotomy, and in the remaining cases, both before and after the craniotomy. The results were as follows: 1) The incidence of abnormal electrocardiogram in head injury was 45% of the cases. Among the abnormal electrocardiograms, nonspecific T change and arrhythmia were the most frequent findings. 2) The electrocardiograms before the craniotomy showed higher incidence of abnormal electrocardiograms than that after the crantiotomy, and nonspecific T change was the most frequent abnormal finding before the craniotomy, while arrhythmia after the craniotomy. 3) The incidence of abnormal electrocardiograms was higher in cases with serious or deeply seated lesions of the brain, and in expired cases.

腦動脈撮影上 Sylvius 點의 正常位置에 關한 硏究 : 第1報 : 角度와 比率에 依한 位置測定法 Part 1: Determination of the Postition by Angle and Quotient

池善豪 대한신경외과학회 1977 Journal of Korean neurosurgical society Vol.6 No.2

A method for determining the normal position of the angiographic sylvian point in the lateral angiographic projection has been devised, by author. The position of the angiographic syivian point has been determined by the angle between two lines from the anterior clinoid process to internal occipital protuberance and to angiographic sylvian point, and the quotient of the measured distance from the anterior clinoid process to angiographic sylvian point to that from the anterior clinoid process to inner table of parietal bone. The 95% confidence limits for mean value of the angle are 50.09±0.90˚and of the quotient 0. 47±0.008. The angiographic sylvian point seems to become lower with advancing age, but remains stationary after growth is completed. The quotient value calculated is independent of skull dimensions. It is assumed that the author's method for estimating the position of the angiographic sylvian point is relatively accurate since the position is determined by the dual components of angle and quotient.

池善豪 대한신경외과학회 1974 Journal of Korean neurosurgical society Vol.3 No.2

In all attempt to evaluate cranioplasty, author reviewed 53 cases of head injuries with cranial defect repaired by cranioplasty. Materials used for cranioplasty were acrylic resin in 42 cases, tantalum in 6 cases and iliac bone in 5 cases. Adequate follow-up observations were obtained in all cases for at least 4 years. The results were as follows; 1) The majority of head injuries were caused by vehicle accident. 2) The majority of skull defects were in the frontal and parietal bones. 3) The interval between primary craniectomy and secondary cranioplasty was from 3 to 4r months in the majority of cases and cranioplasty was performed after fixation of permanent neurologic defect. 4) The indications for the cranioplasty were based upon criteria recommended by Grant and Norcross. 5) Postoperative complications were observed in 3 uses (5.7%).

(3) 後頭窩內合倂症은 意識障碍(89%), 生徵候의 變化(54%) 및 局在徵候(25%)를 보였다. (4) 後頭窩內合倂症의 全例에서 後頭窩의 骨折이 있었고, 骨折의 樣相은 後頭骨의 半軸前後面像에서 骨折線의 位置와 方向에 따라 5가지 型(Fig. 1)으로 區分되었다. (5) 後頭窩內合倂症의 確認된 出血源은 橫靜脈洞(9例)과 連結靜脈(3例)이었다. (6) 後頭窩內合倂症의 後頭下頭蓋切除術에서 後頭窩內壓의 減少를 위하여 大後頭槽를 切開하였고 그 生存率은 82%였다. 後頭窩內合倂症의 共通所見은 後頭部外傷이 同伴된 後頭窩의 骨折과 意識障碍이며 이를 後頭窩內合倂症의 診斷基準으로 採擇하고자 한다. Traumatic complications located within the posterior fossa continue to escape detection for they are not readily demonstrated by the new diagnostic studies and all too often are not considered until found at autopsy. This study is made to stress the importance of recognition and operability for hemorrhages and fluid accumulations in the posterior fossa as a result of cranial injury. Included in the series are all the cases of clinically significant verified complications in the posterior fissa due to occipital trauma. The various posterior fossa lesions seen at the Ewha Womans University Hospital over a course of 3 years (1974~1976) include the following : (1) epidural hematoma(43%), (2)subdural hematoma(25%), (3)subdural hygroma(21%), and (4) cerebellar hematoma(11%). The diagnostic criteria for recognition of complications in the posterior fossa are as follows : there is evidence of local trauma, such as a scalp hematoma, laceration or contusion to the occiput severe enough to produce a fracture of the occipital bone which may cause unconsciousness.

This experiment was performed to investigate the effect of hypothalamic lesions on the blood sugar level in rabbits. Blood glucose in venous blood samples was determined before and 2 weeks after bilateral preoptic regions were destroyed electrolytically. Two weeks after destruction of preoptic nuclei, the blood glucose level was decreased significantly compared to before(76%).

The onset and persistence of headache following spinal puncture is a continual problem to physicians who perform this procedure. There is considerable evidence that headaches following spinal puncture result from low cerebrospinal fluid pressure caused by leakage through the puncture in the dural sac. The author has studied the value and consequences of prophylactic autologous epidural blood patch in postlumbar-puncture headaches. Fifty patients undergoing myelography received prophylactic autologous epidural blood patches to prevent postlumbar-puncture headache; the results indicate a significant reduction in the incidence and severity of this problem compared to a control group, without any significant side effects. Based on the results of this study, author believes that epidural blood patch is a safe and effective procedure of prophylaxis and treatment for postlumbar-puncture headache.

實驗的 手術顯微鏡下 腦塞栓除去術 : 腦塞栓除去術의 時期 A Time Limit for Cerebral Embolectomy

池善豪,辛圭萬 대한신경외과학회 1980 Journal of Korean neurosurgical society Vol.9 No.2

Acute cerebral embolism continues to be a major cause of stroke morbidity in children and young adults. A variety of drugs including, steroids, dextran, barbiturates, and anticoagulants are used in the management of cerebral ischemia, despite controversy over their benefits in clinical and experimental situations. The operative treatment includes microsurgical cerebral embolectomy and cerebral revascularization. Middle cerebral artery embolectomies which have been carried out in human with variable results, have been reported by different authors. In order to define a time limit for cerebral embolectomies before irreversible brain damage has teen incurred, the canine middle cerebral artery was embolized by means of a gutta percha cylinder, 4 mm long by 1.5 mm in diameter, via the internal carotid artery. It was observed that embolectomy of the middle cerebral artery performed between 4 and 5 hours postembolism could prevent the expected cerebral infarction effectually. Middle cerebral artery embolectomy beyond 5-hour periods invariably resulted in severe hemorrhagic infarction with concomitant neurological impairment.

To investigate the functions of the amygdala in limbic system, changes in heart rate and body temperature resulting from electrical destructions of amygdala centralis and piriform cortex were observed in a total of 40 rats varying in weight from 180 to 250g with the use of stereotaxic apparatus (Reyniers and Sons). The results were as follows; 1) Bilateral destructions of amygdala centralis revealed a tendency to increased heart rate and decreased rectal temperature. 2) Bilateral destructions of piriform cortex revealed no changes in heart rate and rectal temperature. Therefore, it is assumed that cardiovascular and temperature responses are not significantly resulted from the electrical destructions of amygdala centralis and piriform cortex.

實驗的 Penicillin-誘發 癲癎

池善豪 대한신경외과학회 1981 Journal of Korean neurosurgical society Vol.10 No.2

The penicillin produces seizures when applied directly to cerebral cortex and, in some instances, when given systemically in large amounts. Most studies with this agent have had as their goal the elucidation of neurophysiological mechanisms underlying seizure activity. The present study was undertaken to explore the biochemical events which take place in the presence of an epileptogenic agent and, in particular, to see whether this agent has a direct effect on passive or active cation transport or an effect on energy production within neural tissues. The penicillin-induced seizure activity has been produced by direct injection of an aqueous penicillin G sodium into the cerebral subarachnoid space in rat. It is assumed that penicillin-induced seizure results from the leakage 'of potassium ions from intracellular compartment and alteration of firing properties of neurons with prolonged depolarization, and disturbances in activities of enzyme involved in glutamine metabolism. Diphenylhydantoin may stimulate cation pumping with activation of (Na^(+)-K^(+))-ATPase enzyme system and this action may be relevant to its anticonvulsant activity.
